Frankish

The Franks or Frankish people (Latin: Franci or gens Francorum) were West Germanic tribes first identified in the 3rd century as an ethnic group living north and east of the Lower Rhine. Under the Merovingian dynasty, they founded one of the Germanic monarchies which replaced the Western Roman Empire. The Frankish state consolidated its hold over large parts of western Europe by the end of the eighth century and the Carolingian Empire and its successor states were Frankish. The Salian political elite were the most active force in spreading Christianity over western Europe.
